ALMA Band 1 Capabilities at Cycle 10

Published: 28 Apr 2023

As described in the ALMA Cycle 10 Proposer's Guide, both spectral-line and continuum observations in Band 1 will be available only with the 12-m Array at Cycle 10, from March 2024 onwards. The Observing Tool will not prevent the submission of projects containing Band 1 ACA observations, but Band 1 ACA (7m and Total Power) observations are not technically feasible at this Cycle. Proposals requiring Band 1 ACA observations should therefore not be submitted.

For more information on the Cycle 10 capabilities, please see Section 4.2 of the Proposer's Guide.
